Abstract
Methods of forming pyrazines from reactants derived from a plant of the Nicotiana species, including receiving an aqueous reactant solution including at least one tobacco-derived cellulosic sugar and at least one tobacco-derived amino acid, heating the reactant solution to a reactant temperature and holding the reactant solution at the reactant temperature for a reactant time to produce a reactant product including at least one tobacco-derived pyrazine, and isolating the at least one tobacco-derived pyrazine from the reactant product. Tobacco products incorporating the tobacco-derived pyrazines are also provided.
Claims20
A method of forming pyrazines from reactants derived from a plant of the Nicotiana species, comprising:
- receiving a tobacco material comprising at least one of a stalk material and a root material of a harvested plant of the Nicotiana species;
- delignifying the tobacco material to form a tobacco-derived pulp, wherein the step of delignifying the tobacco material comprises mechanical pulping of the tobacco material to form a tobacco-derived pulp, and wherein the tobacco material has a moisture content of less than about 15% when it undergoes mechanical pulping;
- hydrolyzing the tobacco-derived pulp to form a hydrolyzed tobacco product comprising residual solids and a liquid comprising at least one tobacco-derived cellulosic sugar;
- separating the liquid comprising the at least one tobacco-derived cellulosic sugar from the residual solids;
- receiving a protein-enriched material from a plant of the Nicotiana species or portion thereof;
- hydrolyzing the protein-enriched material to produce a hydrolyzed product comprising at least one tobacco-derived nitrogen source;
- forming a reactant solution comprising the at least one tobacco-derived cellulosic sugar and the at least one tobacco-derived nitrogen source;
- heating the reactant solution to a reactant temperature and holding the reactant solution at the reactant temperature for a time sufficient to produce a reactant product comprising at least one tobacco-derived pyrazine;
- and
- isolating the at least one tobacco-derived pyrazine from the reactant product.
